I built a WiFi QR Code Generator that runs 100% in your browser

The Problem

Sharing your WiFi password out loud is awkward. Typing it on a guest's phone takes forever. And some passwords are 20+ characters.

The WiFi QR Code Trick

A WiFi QR code encodes your network credentials in a format phones understand natively — iOS 11+ and Android 10+ both support it without any app. Guest scans it, connects instantly.

The QR string format looks like this:
WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;

How I Built It (in 40 lines of JavaScript)

[paste 20–30 lines of your actual JS generator code here]

The key is using a QR library like qrcode.js and building the WIFI: string dynamically from the form inputs.

What I Added for Better UX

  • Show/hide password toggle
  • Network type dropdown (WPA2, WPA3, WEP, None)
  • Hidden network checkbox
  • One-click download as PNG

Real Use Cases

I designed this with 4 scenarios in mind:

  • House guests who can't connect
  • Airbnb hosts who change passwords monthly
  • Office WiFi for visitor access
  • New home setup — print it and stick it on the router

Try It Free

👉 WiFi QR Code Generator — no signup, nothing stored.

I also built a Password Generator and a Browser Privacy Checker as part of the same toolkit.
